Abstract

The optical properties of human aorta were measured during low power argon laser irradiation (~100 mW/mm2) . The delta-Eddington optical model was iterated to determine the optical properties. The results indicated that the transport albedo was nearly constant (-0.96) until the onset of tissue charring, after which it decreased quickly. The optical depth gradually declined (after an abrupt initial increase) until tissue charring when it dropped sharply. The anisotropy dropped initially and increased linearly with time of exposure.
